Description
Jianing Tang and co-authors link stiff neck arteries with weaker thinking and lower brain blood flow in a 2025 paper. Arteries harden with age, and the pulse from each heartbeat then hits the brain with less softening. A new fast scan method can measure stiffness in the carotid artery and how well it damps the pulse, all in about two minutes. The team tested that method in a group of older adults.
Forty volunteers, average age about seventy-three, took part in the study. They received brain scans at a research center, including a measure of blood flow for twenty-five of them. Most also took standard thinking tests, from brief screens to full dementia ratings. The authors compared the artery measures with test scores and flow readings to see whether stiff, poorly damping arteries went with poorer performance.
